Embodiment Construction

[0048] best practice

[0049] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0050] image 3 is a partial sectional view showing an internal structure of a pulley assembly of a compressor according to a preferred embodiment of the present invention.

[0051] As shown in the drawings, a pulley assembly of a compressor according to a preferred embodiment of the present invention includes a pulley 100 , a bearing 200 and an inner ring 400 .

[0052] The components of the pulley assembly will be described in detail as follows.

[0053] First, the pulley 100 receives driving force from an engine. The pulley 100 is in the form of a hollow cylinder, and is connected to an outer peripheral surface of the pulley 100 by a motor-driven belt (not shown in the drawings).

[0054] Specifically, pulley 100 is made of magnesium alloy.

[0055] The pulley 100 includes: a partition wall 110 formed in the pulley ...

Abstract

Disclosed therein are a pulley assembly for a compressor and a manufacturing method of the same, which can prevent possible damages during processing and is fit for high-temperature environment because a pulley is made of magnesium alloy. The pulley assembly includes: a cylindrical hollow pulley made of magnesium alloy; an inner ring formed integrally with the pulley by insert injection molding, the inner ring being fixed to the inner circumferential surface of the pulley and made of a different material from the pulley; and a bearing forcedly pressed and fixed to the inner circumferential surface of the inner ring.

Description

technical field [0001] The present invention relates to a power transmission device of a vehicle, and more particularly, to a pulley assembly of a compressor used in an air conditioner for transmitting driving power to a vehicle and a method of manufacturing the same. Background technique [0002] Generally, a compressor used in an air conditioner receives refrigerant from an evaporator, converts the refrigerant into high-temperature and high-pressure refrigerant gas, and supplies the refrigerant gas to a condenser. [0003] A compressor used in an air conditioner of a vehicle receives driving force from an engine via a pulley assembly and compresses refrigerant. [0004] Conventionally, a compressor for a vehicle selectively controls the driving force of an engine to be transmitted to the compressor using an electronic clutch. [0005] However, the variable capacity compressor does not require an electronic clutch because the variable capacity compressor selectively perfor...
